Sanctuary jurisdictions have existed in the United States since the 1980s. They have recently reentered U.S. politics and engendered contentious debates regarding their legality and influence on public safety. Critics argue that sanctuary jurisdictions create conditions that threaten local communities by impeding federal immigration enforcement efforts. Proponents maintain that the policies improve public safety by fostering institutional trust among immigrant communities and by increasing the willingness of immigrant community members to notify the police after they are victimized. In this study, we situate expectations from the immigrant sanctuary literature within a multilevel, contextualized help-seeking framework to assess how crime-reporting behavior varies across immigrant sanctuary contexts. We find that Latinos are more likely to report violent crime victimization to law enforcement after sanctuary policies have been adopted within their metropolitan areas of residence. We argue that social policy contexts can shift the nature of help-seeking experiences and eliminate barriers that undermine crime victims’ willingness to mobilize the law. Overall, this study highlights the unique role social policy contexts can serve in structuring victims’ help-seeking decisions.

The US government maintains that local sanctuary policies prevent deportations of violent criminals and increase crime. This report tests those claims by combining Immigration and Customs Enforcement (ICE) deportation data and Federal Bureau of Investigation (FBI) crime data with data on the implementation dates of sanctuary policies between 2010 and 2015. Sanctuary policies reduced deportations of people who were fingerprinted by states or counties by about one-third. Those policies also changed the composition of deportations, reducing deportations of people with no criminal convictions by half—without affecting deportations of people with violent convictions. Sanctuary policies also had no detectable effect on crime rates. These findings suggest that sanctuary policies, although effective at reducing deportations, do not threaten public safety.

Activists and academics have been misusing data from the Texas Department of Public Safety (DPS) in studies claiming that illegal immigrants have relatively low crime rates. These studies do not appreciate that it can take years for Texas to identify convicts as illegal immigrants while they are in custody. As a result, the studies misclassify as native-born a significant number of offenders who are later identified as illegal immigrants.

Millions of refugees made their way to Europe between 2014 and 2015, with over one million arriving in Germany alone. Yet, little is known about the impact of this inflow on labor markets, crime, and voting behavior. This article uses administrative data on refugee allocation and provides an evaluation of the short-run consequences of the refugee inflow. Our identification strategy exploits that a scramble for accommodation determined the assignment of refugees to German counties resulting in exogeneous variations in the number of refugees per county within and across states. Our estimates suggest that migrants have not displaced native workers but have themselves struggled to find gainful employment. We find moderate increases in crime and our analysis further indicates that while at the macro level increased migration was accompanied by increased support for anti-immigrant parties, exposure to refugees at the micro-level had the opposite effect.
